WILLIAM JOHN GLEN, OF LONDON, ENGLAND.

REFUSE-CONSUMING FURNACE.

SPECIFICATION forming part of Letters Patent No. 664,039, dated December 18, 1900.

Application filed August 20, 1900. Serial No. 27,491. (No model.)

T0 01/ whom it may concern.-

Be it known that 1, WILLIAM JOHN GLEN, engineer, a subject of the Queen of Great Britain, residing at Ruckholt Lane, Leyton, London, in the county of Essex, England, have invented certain new and useful Improvements in Refuse-Oonsuming Furnaces or Destructors, (for which I have made application for patent in Great Britain, dated January 27, 1900, No. 1,743,) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of furnace which is employed in the consumption of refuse or destruction of waste matter, particularly where the heat resulting is utilized for heating steam-boilers or other economic uses, sometimes called destructors.

Figure 1 shows a vertical sectional view of a destructor plant with the invention applied, taken on the line AA of Fig. 2. Fig. 2 shows a horizontal section of same, taken on the line B B of Fig. 1. Fig. 3 shows a cross-section taken on the line 0 Got Figs. 1 and 2 looking toward the right hand. Fig. 4 shows a plan of the fireplace orfurnace-chamber.

0. indicates the floor or paved delivery-surface for the rubbish.

b b are the openings through which the matters to be burned are delivered onto the hearths c c. The openings 19 b are closed by the doors d d.

e e are openings closed by doors ff, through which stoking-tools can beintroduced to push the matters onto the fire-beds g g, supported on the sets of bars h h.

t' 'i are openings at or about the level of the hearths closed by doors m m, through'which the burned matters can be withdrawn, always leaving a bed of burning fuel ready to start the consumption of next supply of fresh matters.

The hearths c c, which are here shown as a pair, are horizontal or substantially horizontal and are at a level (relatively to the level of the surface of the furnace-bars h, on which the fuel or burning refuse matters at g g rest) about one foot or other convenient height above the top of the fire-bars, so that when the fresh supplies of matters are from time to time pushed forward onto the fire the matters to be burned are always landed on a bed 9 of heated fuel adapted to assist in maintaining the combustion under the draft, generally forced draft, as by pipes 70 is, supplied to the furnace-chambersl Z, and, correspondingly, when the waste matters have been consumed and are raked or drawn off a certain amount of incandescent matter is left to promote combustion of fresh loads, resulting in great economy.

To facilitate stoking, the openings 1' t' or door or doors f f is or are arranged at or about the level of the floor of the hearth c and above the f urnace-bar level.

n 1?. indicate valves for regulating delivery of air to increase draft, and the arrows indicate the direction of flow of the burning gases to the stack.

Having now particularly described and ascertained the nature of my said invention and in whatmanner the same is to be performed, I declare that what I claim is- A refuse-consuming furnace provided with supply, stoke and discharge openings arranged respectively in the top, front and sides thereof, a hearth entirely upon the level of said stoke and discharge opening, and a grate below the level of said hearth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM JOHN GLEN.
